Let's assume you're working on a bike that keeps coming back because of a loose headset. You've checked the adjustment five times, made sure all the required small parts are there, looked at every piece as closely as possible. Have you thought that maybe the head tube might be ovalized? How are you going to check? With your tape measure? Grab your digital caliper from its case and know instantly and authoritatively.
Our caliper measures up to 150mm in either millimeters or inches. It includes a storage case for protection in your toolbox, and the stainless steel frame will keep it looking good (and reading accurately) for years to come.
